Could someone please help me?

When running on Amazon Linux 2, the following error arises:

Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Function Call, monit supports Amazon Linux 2. Detected operatingsystemmajrelease is <2>.

This error leads to the following line:

Troubleshooting, I get the following:

[root@puppetserver etc]# cat /etc/*release*

HOME_URL="https://amazonlinux.com/"

The entry in my Puppetfile is as follows:
mod 'soli-monit', '3.0.0'
